ABSTRACT:
The invention provides an elevating apparatus for raising and lowering a work station holding personnel, equipment, and/or materials between a downward declining, compact retracted position and an upwardly inclining extended limit position. The work station is connected to a mobile support base by parallelogram first and second boom assemblies which are operatively interconnected by a boom assembly coupler and rigid compression link. Thus, raising or lowering the first boom assembly by hydraulic lift means causes the second boom assembly to move correspondingly such that the work station moves vertically, unaccompanied by any substantial horizontal motion, and is maintained in a level attitude throughout the range of motion of the apparatus.
